The Roman roads that served Lincolnshire and the rest of Britain 2,000 years ago have been reproduced in a London Underground-style tube map.

Sasha Trubetskoy, a student at the University of Chicago, has plotted Roman settlements including Lindum (modern-day Lincoln), Bannovallum (Horncastle), and Causennae (Ancaster), and the roads that connected them to the rest of the Roman world during AD 43 to 410.

Ermine Street, running north from London and connecting Lincoln and York which would carry chariots, carts and Roman legions, is shown in green.

The modern A15 from the south to the north of Lincolnshire follows this ancient route.

And the Fosse Way, from Exeter to Lincoln and Cleethorpes - the modern version being the A46 from Bath to Lincolnshire - is shown in red.

There is also an unnamed Roman route running east from Doncaster to Lincoln and then down to Horncastle, a trail still used to this day by visitors heading to the coast.

The roads of Roman Britain

Mr Trubetskoy based the map on historical records, having charted the Roman roads of Europe in June.

He said: "Going into this I really underestimated the Roman presence in Britain.

"This was far more complicated than I had initially anticipated. Not only were there way more Roman Roads in Britain than I initially thought, but also their exact locations and extents are not very clear.

"In a few places I had to get rather creative with the historical evidence.

"Once again the Pelagios digital map was massively helpful to me. Equally as helpful was the site Roman-Britain.co.uk – an absolute treasure trove of information on all things Romano-British.

"I had to do some simplifying and make some tough choices on which cities to include. Again I tried to include larger settlements or forts that were mentioned in more than one primary source.

"Unlike the original Roman Roads map, I was more faithful to the actual geographical location of cities.

"Cluttered areas around Hampshire and the Midlands did have to be shifted around somewhat."

Explaining the English names of the Roman roads, he said: "It’s true, Watling Street and Ermin Way are not exactly Latin-sounding.

"Unfortunately the historical Latin names have been completely lost to history.

"Roman Britain was not as well documented as Italy or Spain, so there is a huge lack of written sources.

"That’s why the names that we do have are actually Anglo-Saxon, and originated a few centuries after the Romans had left."
